Brief Description 

    

Apost is a worm that reaches computers in an e-mail message that is easy to identify, as this message always has the following subject: As per your request.

The effects of Apost are more annoying than harmful, as Apost displays two error messages and sends itself out to every entry in Outlook’s Address Book.

Visible Symptoms 

    

Apost reaches computers in an e-mail message with the following characteristics:

  • Subject:
    As per your request!
  • Message:
    Please find attached file for your review.
    I look forward to hear from you again very soon. Thank you.
  • Attachments: A copy of the file README.EXE, created by the worm in the computers it infects.

Once infection has been carried out, Apost displays a window with a message that seems to be an error of the program WinZip. Apost uses this message to try to divert the user’s attention.

If the user clicks on OK, the worm displays a second window and sends itself out to every contact in Outlook’s Address Book.

Then, it deletes these messages from the Deleted Items folder, in order to remove all trace of infection.
